Spatial Design Network Analysis (sDNA 3D) – Since 2011, it has been developed by Alain Chiaradia, Crispin Coop[er and Chris Webster at Cardiff University and University of Hong Kong. It is a free tool that unifies the use of spatial network analysis in design and research.
In addition to spatial data editing and visualization, ArcGIS provides spatial analysis and modeling features including overlay, surface, proximity, suitability, and network analysis, as well as interpolation analysis and other geostatistical modeling techniques. Python, Web API, .NET: Proprietary. Analytical extensions can be purchased separately.
The software was built under a paradigm of tools that could be used together within a command-line interface to perform GIS database development, geoprocessing, and output functions. [citation needed] ESRI added subsystems for surface processing ("TIN") network analysis ("Network"), and survey data processing ("Cogo"). [citation needed]
This new application included three extensions: 3D Analyst, Spatial Analyst, and GeoStatistical Analyst. These three extensions had become very powerful and popular in ArcView GIS 3.x product line. ArcGIS 8.1 also added the ability to access data online, directly from the Geography Network site or other ArcIMS map services. [42]
Geographic information systems (GIS) play a constantly evolving role in geospatial intelligence (GEOINT) and United States national security.These technologies allow a user to efficiently manage, analyze, and produce geospatial data, to combine GEOINT with other forms of intelligence collection, and to perform highly developed analysis and visual production of geospatial data.
Besides these, there are other open source GIS tools: Generic Mapping Tools – A collection of command-line tools for manipulating geographic and Cartesian data sets and producing PostScript illustrations. FalconView – A mapping system created by the Georgia Tech Research Institute for Windows. A free, open source version is available.
Discussions on geodesign often mention the use of ArcGIS CityEngine, [11] although it is not an analytical tool like GIS. As a crucial tool to enhance 3D shape generation in ArcGIS, ArcGIS CityEngine is the critical product to improve the applicability of GeoDesign, using geospatial information to design or analyze a city.

Net-map was created in 2006 by Eva Schiffer, then a post-doctoral fellow at the International Food Policy Research Institute in Washington, DC. Dr. Schiffer developed the toolbox while working on a project in Ghana with the Challenge Program on Water and Food, a system-wide program of the Consultative Group on International Agricultural Research.
